I'll try to keep this short. I think I'm having a fueling problem. I picked up a JD 5525 that only has 620 hours on it. Filled it up with fresh diesel when I brought it home. Used it for the first time to mow some and it mowed like a champ. About 2 hours in it suddenly lost power and started puffing some blue/grey smoke. I disengaged the PTO and drove it back up to the house. It sat for a little bit and I went back out later and it started and ran fine. I changed the inline filter and the main filter/water separator (both pictured). Fast forward about a week I took it back out to mow and it mowed fine, but after about an hour or so it did the same thing.

It does have a Mr Gasket inline fuel pump (pictured) that the previous owner added. It has a filter on it but I was unable to get it off, so I'll probably just order a new pump and leave the filter off of it. I also know that some of these tractors had the strainer tube inside the tank. Not sure if this one has it or not because I haven't drained the tank to check.

Any ideas, thoughts, or suggestions would be greatly appreciated.

I had the same problem with a 5525. Sputtering above 1900 RPMs. I replaced the rubber hose from the tank all the way to filter. Screen inside tank was dirty. Cleaned when I removed it. Still sputtered. Jd recommended I replaced rubber return hose from header to tank. I didn't do it, it didn't make sense to replace that one. Then I notice by the exhaust where the rubber hose connects to the header at a tee, the connection was loose. Hard to get a wrench in there but you can. I tightened it and problem went away. Maybe just check all hose connections before you replace hose.

That filter on the Mr Gasket pump looks like a standard Ford filter that screws in to the carb on 70's era motors.
3/8" pipe thread ( fine)

Some of those 5 series had no pump....they were gravity fed.

The fix when they had issues was add an electric pump and change all the fuel lines....Apparently the lines would deteriorate or collapse.

I had to replace all "soft" fuel lines on my JD 6415. They became porous and weeped fuel. I used Gates Barricade hose.

Item 20B in post two on my 3320 is a mesh filter that looks like a cigarette. I had trouble with my tractor running good then dying, then restarting after a few minutes. That filter looked like it was coated with molasses. I changed it and tractor appears to run fine. I also had cleaned filter and fuel bowl twice but that hidden filter appeared to be the main culprit. The 3320 has a upside down U shaped tank with a hose that connects each side. The hose was clean but the outlets on the tank were also blocked by scum . Interesting thing is that the tech manual I have does not show the filter, a JD member posted here where it was.

Fuel screen coated with molasses type material indicates possible presence of fungi in your fuel tank. I suggest treating your tractors fuel tank with a fuel conditioner that contains a biocide.
